To fix this error, run the following command from the Run box or from the path where Office is installed (For Office 2010, the path is: C:\Program Files\Microsoft Office\Office14):

Outlook.exe /ResetNavPane

What does Outlook.exe /ResetNavPane do? It clears and regenerates the Navigation Pane for the current profile. Basically, it removes all shortcuts and favorite folders from the Navigation Pane. Not a big deal, as most users leave the default favorite folders in place, but just something to consider.

Here is a complete list of command line switches for Outlook as well as what they do. It also shows how to run them:

This means that outlook in in compatibility mode First, navigate to the following directory: C:\Program Files (x86)\Microsoft Office\Office XX\Outlook.exe right click “Outlook.exe” and then select “Properties” – this should be at the very bottom. From there, go to the “compatibility” tab and uncheck the “Run this program in compatibility mode” check box. Select “apply” and then restart your computer and open up Outlook to ensure “compatibility mode” is completely turned off.

As we used to say when we were young, "Shut Up! No way!". Thank you!!!!! I never realized that was causing the problem "cannot open default email folder". I'm going to pay special attention to that the next time someone asks me about that.

Thank you! This is one of those things like when I realized the ~ilename.xlsx temp file was causing the problem "The spreadsheet is already open by another user" error. I knew about the file for years but never knew it was the cause of the problem.

I have seen the comments about putting in outlook.exe/resetnavpane. I can't find where I put that in to work. I tried the C: drive path and I got of Office 14, but I don't see where I can type that in the computer. I do have Windows 7, Office 2010. Help!!!

Thanks for the help. I found that I wasn't putting a space before the forward slash in the outlook.exe /ResetNavPane. As soon as I did that, it worked. Thanks so much Ingram for posting this information.

Running Windows Vista. Got all the way to Office 14, but that only contains GKExcel, PPT, Word. Office 12 has Outlook.exe.manifest, but what do I do from there? I can't seem to get anywhere. Thank you.

I'm running Windows 8 and that same error message suddenly started showing up. I can't start outlook. I ran that command line and even did a repair install on office..nothing worked. Any ideas? Where does the ResetNavPane executable reside?

Not exactly sure what you mean by that. I did notice that you do not have a space between outlook.exe and /resetnavpane. Outlook.exe is the executable file. /resetnavpane is a command line switch. See this microsoft article for a full list of them and how they work:

Really it works well. However you can get this problem due to problem with Outlook PST file like virus attack,damaged file structure or oversized issues. When you are encountered such types of problem then it can be resolved through a PST recovery tool.

Hi, please help. My outlook cannot open even i use "Outlook.exe /ResetNavPane ". It will asked me to open outlook with safe mode. If choose yes. Then, it said unable to open again and start the "Detect and Repair". Finish installing " Microsoft Office Professional Hybrid 2007", then nothing happens. Hope you can understand the problem and help me. Otherwise, do i need to format my pc @ install new Microsoft Office ?

I really like the ability to automatically feed your blog into your email newsletter. However, is there a way to easily add custom content to each blast. In my email blasts, I would like to not only include the recent post on the blog, but some additional call to action.

Cannot launch ms Outlook in ms office 2010 in windows 7. Word and other programs work ok. Say there is a problem with C:\users\chard\AppData\Local\Microsoft\Outlook\Outlook.pst
I uninstalled outlook and reinstalled but same problem....????
Thank you

The command worked. I put a short cut with the command on the desktop for the user and he is happy. Is there a fix so the command does not need to be there? Or do I just re-install MSOffice on his PC and see what happen? My user is a salesperson and he is on the road most of the time, so I would like to try to fix it without him having to come into the office.
